Abstract : DYSCO is an interactive computer program which allows a user to model the dynamic and aerodynamic behavior of rotorcraft and other aerospace structures. The program provides user-oriented modeling procedures and data base management for dynamic analyses of coupled systems of independently modeled components. Each component is a system of second-order ordinary differential equations. The user employs modules from an expandable library of algorithms to formulate and couple components and to obtain solutions of the couple system.
